	* gcc-interface/Make-lang.in: Update dependencies.
	Remove s-traceb and tracebak objects from gnat1 and gnatbind (not used).
	Remove s-tasdeb and s-vaflop rules (not used).

2012-04-26  Olivier Hainque  <hainque@adacore.com>

	* gcc-interface/targtyps.c (WIDEST_HARDWARE_FP_SIZE): Default to
	DOUBLE_TYPE_SIZE instead of LONG_DOUBLE_TYPE_SIZE.

2012-04-26  Hristian Kirtchev  <kirtchev@adacore.com>

	* a-calend.adb (Day_Of_Week): Keep the internal
	usage of UTC_Time_Offset consistent with Time_Of and Split.
